Abstract

PURPOSE:To make it possible to dispose of a combustible waste plastic safely and efficiently without catching fire, by sending a high-temp. superheating steam into a furnace and throwing the waste plastic into the furnace to thermally melt it by the high-temp. superheating steam and thereafter solidify. CONSTITUTION:A wet steam produced by a boiler 1 is sent to a superheating room 2 to superheat at 300-400 deg.C and then discharged downwards out of a spray pipe 3 to heat a furnace 4. After preheating the furnace sufficiently, an inlet door 6 is opened to throw a waste plastic 8 in it through an inlet 5. The melted waste plastic flows into a receptacle 6. As the superheating steam has 10 times energy as strong as a hot air, it can thermally melt the waste plastic efficiently, for its energy as a latent heat of varporization is exchanged with the waste plastic, and not a heat exchange of convection. Moreover, it is safe because a combustible substance never flames in the steam.

Description

【発明の詳細な説明】 「産業上の利用分骨」 本発明は廃プラスチックを熱熔融し、固型化して再生原
料、燃料に利用し又は埋立用とする方法である。DETAILED DESCRIPTION OF THE INVENTION "Industrial Utilization" The present invention is a method of heat-melting waste plastics, solidifying them, and using them as recycled raw materials, fuels, or for landfilling.

融する方法であった、熱風は比熱が少ないため大量の熱
風を送らなければならず、熱風の温度を上げて能力を上
げようとすると、廃プラスチックが着火し極めて危険で
あった。``Conventional technology'' Conventionally, the method for thermally melting this type of waste plastic was to use hot air to melt it.Since hot air has a low specific heat, it was necessary to send a large amount of hot air. If you tried to lift it, the waste plastic would catch fire, making it extremely dangerous.

処理する方法を提供することである。``The interlayer point that the invention seeks to solve'' As mentioned above, melting flammable waste plastic with hot air has the risk of ignition, and while low-temperature hot air is safe, it has the disadvantage of not being efficient. Another object of the present invention is to provide a method for safely and highly efficiently processing flammable waste plastics without igniting them.

安全である。``Means for Solving the Problems of the Invention'' A method for thermally melting waste plastics, in which high-temperature superheated steam is sent into a furnace, waste plastics are put into the furnace, and the waste plastics are thermally melted and solidified by the high-temperature superheated steam. ” In the present invention, the wet steam generated in the boiler is further heated to become superheated steam of 300°C to 400°C and is blown into the furnace, but this superheated steam has 10 times the energy of hot air.
Rather than using convection heat exchange, the waste plastic exchanges energy in the form of latent heat of vaporization, resulting in highly efficient thermal melting.In addition, combustible materials are safe because they will never burst into flames in steam.

気中に放出される。The wet steam generated in boiler 1 enters superheating chamber 2 and reaches a temperature of 300°C.
After being sufficiently preheated, it is heated to ~400°C and is discharged downward from the spray pipe 3 to heat the inside of the furnace 4.
The waste plastic 8 is inputted from the input port 5 by opening the input port n6. The molten waste plastic 8 melts and flows into the receiving box 6. When the receiving box t is full, the exit door 9 is opened and taken out. Ru.
